20 Spellbinding Animal Migration Photos

One of a select few species that still migrates daily, five million jellyfish move gracefully across a lake in Palau everyday as they follow the path of the sun. The remarkable spectacle ends at night, when the jellyfish sink 45 feet below the surface and find the necessary nutrients to do it all over again the following day.

Species of the Day: The Common Potoo (Nyctibius griseus). This peculiar nocturnal animal is designed to survive because it is one of the best camouflaged birds in the world. It spends its day resting, appearing to be part of the trunk of a tree. While at dusk it hunts large flying insects with its large mouth wide open. Photo: The Lilac Breasted Roller
